Nyan Cat is a boy. Tac Nayn is a girl. Based on the mobile game, when Tac Nayn drinks the nrg drink, she gets a bow. Now this could be wrong; Tac Nayn could be.... Jack, আপনি can সম্পাদনা this out, right? Assuming Nyan Cat Don't get no bow, I rest my case
Nyan cat is a boy, and Tac Nayn is a girl, proven দ্বারা Nyan Cat হারিয়ে গেছে in Space, a Nyan cat app, where আপনি can play as Tac Nayn. When আপনি get the Adrenaline power up for Tac Nayn, (Adrenaynline) their eyes go Kawaii and a পরাকাষ্ঠা bow appears on their head. This inspired me to make a custom called "true Nayn" which has eyelashes, a bow, and a curious expression on 'her' face.
